Wolff-Parkinson-White syndrome (WPW)?,”in WPW, an accessory pathway conducts depolarization directly from the atria to the ventricles without traversing the AV node. Afib occurs in 10-30% of individuals with WPW, and is a potentially life-threatening emergency. Persistent Afib with rapid ventricular response in patients with WPW can ultimately deteriorate into ventricular fibrillation (VFib).Acute treatment is aimed at prompt control of Vfib and termination of Afib as follows:- Hemodynamically unstable patients require immediate electrical cardioversion- For stable patients
rhythm control with antiarrhythmic drugs such as IV ibutilide or procainamide is preferred.”
